17 Claims.

This invention relates generally to coin controlled devices of the type used on vending machines, automatic phonographs and like apparatus, but more particularly to a multiple magazine switch machine for governing the operation of such apparatus in accordance and commensurate with the deposit of different denomination coins.

One of its objects is to provide an electricallygoverned, multiple coin device of this character which is simple, compact and inexpensive in construction which is eflicient and reliable in operation, and which is so designed as to positively register and automatically pre-set the device as determined by the value of the coins deposited, whether a nickel, dime or a quarter, by a single electric impulse or contact of the coin or coins as they pass through their respective coin chutes,

assuring the patrons full value for the deposits made.

It has for another object to provide a unitary, multiple coin device embodying an electricallygoverned ratchet mechanism which is so designed and constructed as to selectively feed the ratchet mechanism a predetermined distance in accordance with the coin values deposited and in turn govern the duration of closing of the switch controlling the apparatus to which the mechanism is applied.

Other features of the invention reside in the construction and arrangement of parts hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a front view of the magazine switch device with the cover plate removed and the parts in a normal, switch-opened position. Figure 2 is a similar view with the parts in switch-closed position, after the deposit of a nickel. Figure 3 is a similar view with the full lines showing the position of the parts after the deposit of a dime and the dotted lines showing the position of the parts after the deposit of a quarter. Figure 4 is a fragmentary front View showing the means for latching those parts of the device in switch-closing position during the maximum movement of the segmental pinion. Figure 5 is a diagrammatic view of the electrical circuits controlled by the coins deposited and showing the independent discharge chutes equipped with switches momentarily closed by the passage of coins therethrough.

Similar characters of reference indicate corresponding parts throughout the several views.

In the embodiment of my invention shown in the drawings, this coin-controlled device is designed for actuation by nickels, dimes and quarters to initiate the closing of the circuit of an automatic phonograph or like apparatus to which the device is attached, the denomination of the coins deposited, by a single electrical impulse, governing other mechanism for controlling the duration of closing of such circuit to accordingly give the patron the full value for the deposits made. For example, should the coin device be employed in connection with an automatic phonograph and a nickel be deposited for the playing of one selected record, the controlled circuit will remain closed until that record is played; should a dime be deposited, the controlled circuit will automatically remain closed until two records are played; and should a quarter be deposited, the controlled circuit will automatically remain closed until five records are played. In other words, the denomination of the coins deposited automatically governs my novel mechanism initiated by the coins for accordingly predetermining the duration of closing of the circuit to be controlled.

Referring now to the drawings, 10 indicates a coin selector of any well known construction into which the various denomination coins are deposited, the acceptable coins passing through nickel, dime and quarter discharge chutes ll, l2 and I3, respectively. Located in these chutes are companion switches l4, I5 and I6 which are adapted to be momentarily closed by the respective coins and which govern the closing of other circuits hereinafter described responsible for predetermining the duration of closing of a switch ll included in the control circuit of the phonograph or like coin-controlled apparatus.

The various working parts of my coin-controlled device, including the switch are mounted on a base or casing l8, and in its preferred construction such device consists of a ratchet wheel i9 mounted on a stud 20 and having a helical spring 2| connected thereto for constantly urging it to turn in a clockwise direction. Pivoted intermediate its ends at 22 alongside the ratchet wheel is an escapement pawl 23 which is substantially bell crank in shape and which is provided on one arm thereof with a tooth or pallet 24, while its other or depending arm has a revolvable toothed detent or segmental pinion 25 rotatably mounted thereon in the plane of the ratchet wheel and having a helical-spring 26 connected thereto for constantly urging it to turn in a clockwise direction. A spring 21 connected at one end to this pawl and at its other end to the base l8 normally urges the pawl to rock in a direction to engage its pallet 24 with the ratchet wheel to prevent clockwise movement of the latter and at the same time release the segmental pinion from meshing engagement with such wheel. Reversely, when the ratchet-holding pallet is withdrawn from engagement with the ratchet wheel, the segmental pinion 25 is brought into engagement therewith and the spring-urged movement of the ratchet wheel in a clockwise direction turns the pinion in a counter-clockwise direction. The movement of the pawl to this position is initiated upon the deposit of a coin and for this purpose an electromagnet 28 is provided in operative relation to the pallet-bearing arm of the pawl which acts as an armature. The nickel coin switch I4 is included in the circuit of this electromagnet and serves to momentarily energize it upon the passage of the nickel through the companion coin chute ll. Such movement transmitted to the pinion by the temporary release of the ratchet wheel, however, is controlled in accordance with the value oi. the coin deposited by the provision of adjustable,

-. coin-governed stop means, the pinion having five teeth thereon with one tooth representing a nickel, two teeth representing a dime, and the five teeth rep esenting a quarter, whereby the stop means automatically functions, depending on the coin value deposited, to arrest the movement of the pinion and the ratchet wheel after the escapement of one, two or five teeth.

Projecting from the segmental pinion 25 diametrically opposite the teeth thereof is a laterally-bent lug 29 which normally abuts at one radial edge against the opposing edge of the lower arm of the escapement pawl 23 to hold the pinion in position so that its first or nickeltooth will register with the ratchet wheel upon the magnetic release of the pawl, the spring 26 constantly urging the turning of the pinion to such position. At its opposite radial edge this pinion-lug is adapted to engage one or another of three stops for limiting the turning of the pinion one, two or five teeth depending upon the denomination of the coin deposited. Two of these stops, indicated at 30, 3| are applied to the upper arm of a vertically-swinging lever 32 pivoted intermediate its ends at 33 to the base l8 at one side of and below the pinion-axis, the outer stop 39 limiting the nickel-registering travel of the pinion and the inner stop or shoulder 3|, which is laterally offset from the firstnamed stop, limiting the dime-registering travel of the pinion. The lower arm 34 of this lever functions as an armature and extends between opposing magnets 35, 36 to be attracted to one or the other of said magnets when they are independently energized and accordingly rock the stop lever 32 in one direction or the other. The magnet 35 is included in the circuit of the dime switch l5 and is momentarily energized upon the deposit of a dime to cause the stop lever to swing in a direction to bring its outer stop 39 clear of and its inner stop 3| into the circumferential path of the pinion-lug 29 to arrest the movement of the pinion after a predetermined distance of travel. The magnet 36 is included in the circuit of the quarter switch I6 and is momentarily energized upon the deposit of a quarter to cause the stop lever to swing in the opposite direction to bring both stops 30, 3| clear of the path of the pinion-lug 29 and allow the latter to abut against a fixed stop 31 pro-.

jecting from the face of the base [8 and so positioned as to permit the pinion to travel its maximum distance or five teeth. A

A spring 39 connected to the stop lever inline with its pivot serves to normally urge the lever to its neutral position with its lower arm disposed centrally between the magnets 35, 36 and the outer stop 39 of the lever in line with the pinionlug, and subsequent to the momentary energize.- tion of either magnet this spring restores the lever to its initial position The stop lever 32 also has an arm 39 projecting upwardly therefrom in spaced parallel relation to and radially offset from the stop arm thereof and atits free end has an insulated fork 49 which embraces the leaves of a normally open spring switch 4| included in the circuit 01' the electromagnet 28. Whenever the stop lever is actuated in one direction or the other in response to the energization of the coin-governed magnets 35, 36, this switch is simultaneously closed to in turn energize the electromagnet 28 to efiect the temporary release of the pawl 23 from the ratchet wheel l9 to cause the latter to transmit the required movement to the pinion 25. In the case of the deposit of a quarter coin, an appreciable time is required to revolve the pinion five teeth and it is therefore necessary to latch the stop lever in its released position to maintain the switch 4| closed and the pawl-releasing magnet 28 energized during the five tooth travel of the pinion. For'this purpose, a pivoted latch 42 is provided having a notch or shoulder 42 in its top edge with which a locking lug 43 projecting laterally from the lever arm 39 is adapted to engage in that position of the lever eflected by the energization of the magnet 36. A spring 44 connected to this latch normally urges it to swing upwardly toward its latching position. The free end or nose of the latch 42 is disposed in the circumferential path of travel of the pinion-lug 29 adjacent the fixed stop 31 so that just prior to such lug encountering such stop, it strikes the latch and swings it downward to unlatch it from the lever arm 39 and allow the parts to return to their initial or normal position.

The switch H, which is of the yieldable lead type and which controls the operation of the apparatus to which the coin device is applied, is positioned alongside the ratchet wheel in operative relation to the insulated tappet lug 45 extending from the outer arm of a vertically-swinging lever 46 pivoted intermediate its ends on the ratchet wheel and stud 20 and having a spring 41 connected thereto for normally urging the lever in a direction to bring the tappet lug away from the switch to effect its closing. A stop pin 48 projecting from the face of the base l8 and engaging a slot 49 in the switch-controlling lever serves to limit the movement of such lever in opposite directions. On its inner arm this lever has a laterally-bent lug 59 and projecting from the face of the ratchet wheel I9 is a cooperating trip pin 5|, which, when the ratchet wheel moves in a clockwise direction as a result of the deposit of a coin or coins in the device, causes a receding of the pin from the lug a distance of one, two or five teeth, depending on the denomination of the coin deposited, with the spring 41 acting to turn the lever 46 in a direction to cause the switch I! to close. At a predetermined time in the reverse or counter-clockwise movement of the ratchet wheel, its pin 5| engages the lug 50 and turns the switch-controlling lever in a direction to open the switch.

The counter-clockwise movement of the ratchet wheel is effected by a feed pawl 52 which is normally disengaged from such wheel but which is adapted to be brought into and out of engagement with the wheel to turn it a distance of one tooth after each unit operative cycle of the coincontrolled apparatus has been completed. To accomplish this end, this pawl is pivoted at 53 to one arm of a vertically-swinging lever 54 fulcrumed at 55 on the base l8, while the other arm thereof is adapted for connection, for example, to a reciprocable part 56 of the coin-controlled apparatus and which part functions to rock said lever and accordingly bring the pawl 52 into operative engagement with the ratchet wheel. The pawl is urged toward the periphery of the ratchet wheel by a spring 51 and a stop pin 58 is provided for limiting and maintaining the pawl in proper relation to the ratchet wheel. Thus, at each reciprocating stroke imparted to the part 56 at the end of a unit operation of the apparatus to which this coin device is applied, the ratchet wheel is moved a distance of one tooth in a counter-clockwise direction and when the lever 54 has been rocked a number of times equal to the number of unit or nickel coin values deposited, the ratchet wheel is turned backward a corresponding number of teeth to accordingly eiTect the automatic opening of the switch I! and the stoppage of the coin-operated apparatus after all the deposited coins have been registered and full value received therefor.
